You Don't Know Jack

It's just as the description says, you have to play the game for 5 hours without getting a single trophy. Unfortunately you actually have to be playing the game for 5 hours (you can't just leave it on the main menu or paused in game). The quickest way I have found to attempt to get this is to play through the episodes in order and make sure to get all the other offline trophies but the episode related & prize related trophies by the time you get to episode 31. After you finish episode 31 and get the Discovered Gauntlet Of Fire trophy, play the next 4 episodes (up to 35), then choose episode 38 (skip 36 & 37) and play the rest in order through 73. By the time you get to 73, you should have played for over 5 hours without getting a trophy at that point. If you haven't, then just replay some of the episodes you already finished until you reach over 5 hours. Once you finally finish you 5 hours without getting a trophy, this trophy will pop for you!
